Peter, is your enter key broken? You seem to be typing all your text in a single unreadable paragraph.

Accept all the memory up front and boot slowly, but reliably 2. Use thus "unaccepted memory" mechanism, boot fast, but risk that the VM loses a bunch of memory. If the guest can't even boot because of a lack of memory, then the pre-accepted chunk is probably too small in the first place. If the customer screws up, they lose a bunch of the RAM they paid for. That seems like a rather self-correcting problem to me.
